ASGE 2023 Masterclass EUS: Principles, Best Practices & Innovative Paradigms (Virtual)

Video Transcription

Video Summary

In this video, the speaker discusses the use of diagnostic endoscopic ultrasound (EUS) and provides tips for performing EUS. They emphasize the importance of knowing the equipment, including understanding the spatial relationship of the scanning range to the anatomy. They also discuss two important buttons on the equipment: the gain button, which adjusts the brightness of the image, and the frequency button, which determines the degree of penetration of the waves into the tissue. The speaker suggests using a middle frequency for general scanning and lower frequencies for looking at extramural tissues and higher frequencies for intramural lesions. They then discuss the importance of knowing the layers of the gastrointestinal tract and provide tips for examining different organs. The speaker also discusses the uses of EUS in diagnosing submucosal lesions, chronic pancreatitis, and biliary disease, and provides recommendations for when to perform an ERCP. Additionally, they mention the limitations and potential complications of EUS. The video concludes by emphasizing the need for a pretest probability and clear diagnostic question when using EUS for diagnosis. No credits were mentioned in the video.
